Episode 162 — DNS, VLAN/VXLAN, Proxies, MTU, QoS, and Time Sync Errors

Episode 164 — Troubleshooting Automation and Orchestration — Mismatches and Failures

This episode addresses problems in automation and orchestration workflows. Mismatches can occur when scripts or templates are out of sync with infrastructure changes, causing failed deployments or inconsistent configurations. Deprecated API calls or incompatible orchestration sequences can halt processes entirely. Failures may also result from missing dependencies, misordered tasks, or security policy conflicts. We also outline resolution strategies like reviewing automation logs, updating scripts for API compatibility, and revalidating orchestration workflows in test environments. For the Cloud+ exam, understanding how to diagnose and correct these issues is key to maintaining reliable, scalable infrastructure management.

Episode 163 — Network Tools — Using Ping, Tracert, IP, NSLookup, Netstat, and More

In this episode, we explain how to use essential network troubleshooting tools effectively. Ping verifies connectivity and measures latency, while Tracert or Traceroute maps the path packets take through the network. IP or ifconfig commands show network interface configurations. NSLookup or dig queries DNS records directly to diagnose name resolution issues. Netstat displays active connections and listening ports to detect unusual activity or service problems. We also explore advanced tools like packet capture utilities, curl for HTTP testing, and OpenSSL for certificate inspection. On the Cloud+ exam, familiarity with these utilities and their output is necessary for rapid problem identification and resolution.

Episode 162 — DNS, VLAN/VXLAN, Proxies, MTU, QoS, and Time Sync Errors

This episode looks at multi-layered networking issues that can disrupt cloud services. DNS errors may involve incorrect records, propagation delays, or misapplied DNSSEC settings. VLAN or VXLAN misconfigurations can isolate workloads unexpectedly. Proxy issues may break application access or degrade performance. MTU mismatches can cause dropped packets or failed connections, while incorrect QoS policies may throttle critical traffic. Time synchronization errors, if left unresolved, can cause authentication failures and logging inaccuracies. We also cover tools and techniques for diagnosing each issue, from DNS dig commands to packet analysis and QoS policy reviews. For the Cloud+ exam, knowing how to pinpoint and resolve these network-layer problems is crucial for maintaining both availability and performance.

Episode 161 — Troubleshooting Load Balancer Behavior — Protocols, Headers, Front/Back Ends

In this episode, we cover diagnosing issues with load balancers in cloud environments. Problems can arise when the load balancer is configured with the wrong protocol, causing mismatches between client and server communication methods. Incorrect handling of headers—such as missing X-Forwarded-For or session cookies—can break client tracking or routing logic. Misconfigurations in front-end listeners or back-end pools can cause requests to fail, be misrouted, or overload specific servers. We also examine testing methods, including health checks, packet captures, and configuration audits to isolate issues. In the Cloud+ exam, you’ll need to identify how to troubleshoot these load balancer elements to restore reliable, optimized traffic distribution.

Episode 160 — Routing and NAT Problems — Static, Dynamic, VPN, Source/Destination

In this episode, we discuss how routing errors and Network Address Translation (NAT) misconfigurations can impact connectivity and data flow. Static routes may be outdated or incorrectly entered, while dynamic routing protocols can fail due to misaligned configurations or missing updates. NAT problems may involve incorrect source or destination mapping, breaking application communication. We also cover troubleshooting techniques like route table reviews, traceroute analysis, and NAT rule inspection. For the Cloud+ exam, knowing how to correct these issues ensures secure and efficient network operation.
